Physical therapy, in brief, is often referred to as 'rehab' (5 letters). Rehab is a form of medical treatment that focuses on restoring physical function and mobility to those who have been injured or disabled. It is a type of therapy that uses exercises, stretches, and other techniques to help patients regain strength, flexibility, balance, and coordination. Rehabilitation can also include the use of assistive devices such as wheelchairs, walkers, and braces. Physical therapists work with patients to develop individualized treatment plans that are tailored to their specific needs.
